SBRING-WHEEE Specification of Bette-rs Patent;

Patented-Sept. 30', 191 3.

Application filed January 2,.1912. Serial No. 669,063..

Tacit whom it may concern; e l 7 Be it known that Roonm G... Bnnnnnns,

a citizen of the United States, residing at Easton, inithecounty of? Mason and- Stateof Illinois, have invented a new and useful Spring-Wheel, of which the following is a specification- V e The presentinvention to prov de;

,Wheel: structure in which the commonly used.

pneumatic tiresare replaced; by- V a punctur eproof tube, preferably fashioned from metal,

and ordinarily inelastic, the resiliency of. the;

wheelbeing afforded by means ofsprings:

changes in. the precise. embodiment of inven-- 1 tion herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawingsgrliigure ll showsthe invention in fragmental side; elevation; Fig. 2 is a radial sectionupon the line A.B of Fig. 1; Fig. 3v isa. perspective of one, of the spring holders; Fig. 4 is a perspectiveof one of the springs; and Fig. 5 is a section upon.

the line CD of Fig. 3, a portion of one of the springs, and a portion of the rim being shown as added details.

In the accompanying drawings the numeral 1 denotes the hub, and the numeral 2 denotes the spokes, the spokes 2 supporting the rim, which is acomposite structure, the rim including a felly 3 and a felly band 4, surrounding the folly. Yieldably supported upon the T1111, and spaced therefrom, is the tire which, like the rim, is a composite structure. The tire includes an inner tube 5, having a base 6, and a cover 7 surrounding the inner tube 5. The inner tube 5 and its base 6 are preferably fashioned from steel, this portion of the structure therefore, being puncture-proof and inelastic. The cover 7 is ordinarily fashioned from rubber, leather, canvas or the like. It adds little, if any resiliency to the structure, and is not relied upon to efiect this end. Its principal functionis to render thew-heel noiseless, v.ation.

The springs which serve/to hold the tire .yieldably spaeed beneath the rim, may be assembled with the tire. with the. rim in desired manner. In the present instance, spring holders are. applied to the band 4t and to. base 6 of the inner tube 5. One; ofv these springholders. is. shown in Fig. 3'. The spring holders are substantially alike, but for convenience in; description, .those holders. which are connected with the base 6; will be denoted by the numeral 8, those holders which are connected with the folly band-dbeingdenotedby the numeral 9. Each; holder, then, is in the. form of a plate, '5 and plVOiit elements: 10 are extended through openings 11 in the holders 8, to unite the holders 8. at oneend with the base 6. of .the. tube 5.. Other pivot elements 12 enter the. corresponding openings 11 in the holders 9, to; assemble. the holders 9' pivotally with the; folly band 4... The lateral edges u of the holders are equi-pped'with inwardly in oper projecting,- overhanging flanges-14. The springs-denoted generally by the nuv meral15, are preferably Gill'hliCfitl. form, the convolutions thereoffbei-ng rectangular. The .outer convohttion 16; of the spring 15. is en-. gaged beneath the. flanges 14 of the; holder 8, the inner convolution 17 being engaged beneath the flanges 14 of the holder 9. The [convolutions 1.6. and 17 terminate. at their jfgree ends in'angul'arly disposed fingers 18 and 19, respectively, the fingers being terminally equipped with eyes 20. Securing elements 21, preferably taking the form of screw bolts, are passed through the eyes 20, and through openings 22 in the holders 8 and 9, the securing elements 21 entering the base 6 of the tube 5, and entering the folly band 4, as will be clearly appreciated from an inspection of Fig. 5.

Noting Fig. 1 it will be seen that when the vehicle wheel moves over the ground, the springs at the bottom of the wheel will be compressed, the springs at the top of the wheel being elon ated. The tire will, therefore, be yielding ly and resiliently supported. Owing to the rectangular form given to the convolutions of the springs 15, the springs will afford the desired vertical resiliency, without, permitting the tire to have an undesirable amount of lateral movement with respect to the rim.

When it is desired to remove one of the springs 15, the securing elements 21 are disengaged from the telly-band land from the base 6 of the inner tube 5, whereupon the holders 8 and 9 may be swung outwardly, at their free ends, the holders moving upon pivot elements 10 and 12 as centers; It is to be noted that when the securing elements 21 are disengaged from the base 6 of the inner tube, and from the telly band .4, thev 10 free ends of the convolutions 16 and 17 are set free, since the securing elements 21 no longer engage in the eyes 20. The springs 15 may thereupon be slid endwise, from beneath the flanges 1 1.

15 In replacing a spring, the convolutions 16 and 17 are engaged beneath the flanges 14:, the eyes 20 being alined with the openings '22. The holders 8 and 9 are then swung inwardly to the plane of the wheel, and the 20 securing elements 21 are passed through the eyes 20, and through the openings 22, into engagement with the telly band 4 upon the onehand, and into engagement witlrthe' by the springs 15, the device may be used 7 'upon the roughest roads, without danger of "injury through puncture, and without danger to the running gear, due to excessive 40 jolting.

Having thus described the invention, what is claimed is 1. In a device of the class described, a rim; .a tire; holders mounted upon the rim and upon the tire for lateral swinging movement, thereby to dispose the holders transversely ofthe tire and of the rim; a spring adapted to be assembled with the holders and be removed therefrom when the holders are disposed transversely ofthe tire and of the rim, the holders having spring engagmg elements for receivingthe spring slidably; and means for securing the holders against swinging movement and in alinement with the rim and with the tire.

2.. In a device of the class descr1bed,a

tire; a rim; holders mounted upon the tire and upon the rim to swing transversely of the tire and of the rim; springs engaging the holders and removable therefrom when the holders are disposedtransversely of the tire and of the rim; spaced elements connecting the holders with the tire and with the rim respectively, one connection element of each holder constituting a pivotal mounting for the holder, and the other connecting element of each holder constituting means for securing said holder against swlnglng movement, the last'specified connecting element of each holder being engaged with the spring to prevent relative movement between the sprlng and said holder. 7 In testimony that I claim' the foregoing as my own, Ihave hereto affixed my signature in the presence of two witnesses. l
